We have a NetApp FAS2020 with a fiber-connected shelf and use NFS for the VMware VMs stored on it. We don't run UV on it, though. The problem with running an I/O intensive app like UV on a SAN is that there's no way to predict the concurrent I/O demands that will be placed on the SAN by other virtual machines at any given time. To get predictable perfomance from an I/O intensive app, direct-attached storage is usually going to be the best bet. NetApp has recently addressed this issue, though, with a product called Flash Cache, which I believe can be retrofitted into existing FAS models. Flash Cache stores frequently accessed data on SSDs that sit between the network and the hard drives.

Googling during my lunch... I'm guessing this is the box you have, or something similar: http://www.netapp.com/us/products/storage-systems/fas3100/fas3100-tech-s pecs.html You might try disabling that RAID DP stuff they have and just running RAID 1 or RAID 10, as a first step in your process of elimination. Any of the options I suggested are a project. Reconfiguring just the disk shelf is less work than reconfiguring a host for it to run on. If you are running a fiber link to it, you probably can't use NFS, so that idea is out. If you are doing any de-duplication/compression, turn that off too. _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
